Ladies who lunch

MICHELLE Obama (above) is keeping things healthy. The former first lady, known for her White House vegetable garden, was spotted having lunch with Food Network’s “Barefoot Contessa” Ina Garten at the Mark Hotel. “The two were chatting and laughing over a light meal at Jean-Georges [ Vongerichten’s] restaurant within the hotel,” says a spy. Obama appeared on Garten’s show last year. Interestingly, Garten once worked at the White House as a staff member of the Management and Budget office in 1978.
